Title: BTC hacked from blockchain wallet Post by: bxmail on August 29, 2019, 04:21:44 AM Skycity Aug 27, 2019 22:50 EDT
This morning I found my BTC balance 0. But it must be 0.035 BTC on it (about 350 USD). What happened? I did not send anything or even accessed my BTC wallet. Please HELP. Greg (Blockchain) Aug 28, 10:13 EDT Hello, I'm very sorry to hear about this. You may have some type of malware on your computer that resulted in your funds being stolen because your private information was somehow obtained. One of the most common types of these are browser extensions posing as bitcoin price tickers that are actually stealing your account information. There's also the possibility that you visited a phishing site posing as Blockchain. We've also heard of computer viruses that detect when an address is in your clipboard, and replace the one you wanted to use with an address controlled by this malicious party. By design, Blockchain never has access to users' accounts or funds. If you keep your password and private key backups secure, then your funds are always safe with us. Since this information has been compromised, be sure to never use this wallet or any addresses contained within it. I'd also highly advise against using the same password again. I'm truly sorry that you had funds stolen from you. That certainly is an extremely frustrating experience. If you?d like to learn more about how our wallet works, please visit: https://www.blockchain.com/learning-portal/wallet-faq. Skycity Aug 28, 23:54 EDT Hello, None of what you mentioned really occured, it was probably a breach in your security system. And, yes, again as you mentioned, that certainly was an extremely frustrating experience. But what is more frustrating is that you hold no responsibility. I was totally sure that my funds would be safe with you, blockchain.com wallet was chosen, because I trusted you. But this is the point where trust ends. That was not my fault. My computer is always double-checked and secure, and I never visit phishing sites or extensions. Such response from you, no help or compensation offered from your side, makes it even more frustrating. I will never use again and will discourage other people to use your service. I am also going to make this situation and our conversation public.

Check your email, whenever you login or have new transactions from your blockchain account they usually send out notifications. The hacker can't get your private key because on blockchain's wallet they don't give out private keys anymore unless you've been using their wallet since the old version and your old addresses was imported.

Title: Re: BTC hacked from blockchain wallet Post by: lepbagong on August 29, 2019, 06:15:51 AM Most of the lost funds in the wallet, it is very certain because of mistakes that we do not realize.
because many methods of people who are not responsible for doing tricks so that people's funds can be taken in his wallet. clearly that the wallet is absolutely certain to be safe, now you only need to be introspected whether you have done anything unknowingly which resulted in funds being taken. some easy methods to do are: -Don't open email links that you don't recognize. -get used to opening that often do through bookmarks, do not manually through google because a lot of data that resembles.

Title: Re: BTC hacked from blockchain wallet Post by: mocacinno on August 29, 2019, 06:43:23 AM I really, really, really don't like any online wallet, exchange wallet, casino wallet,... Basically any wallet that doesn't make sure you're the only one in controll over your private keys, is open source and has a sufficient recovery scenario in case they ever dissapear is a big no-go for me...
So, in this case, i'm defenately NOT defending blockchain.info/com. However, i do urge you to see things from their perspective: how many emails do you think they get on a daily basis about people that have been hacked and try to blame them for their loss? I'm pretty sure 99,9% of those cases actually involve a user installing malware, falling for a phising attack or exposing their seed/private key/blockchain credentials. If a helpdesk employee gets 1000 complaints, and 999 of them are a PICNIC (problem in chair, not in computer) problem, it's pretty normal that he misses the 1 actual complaint. That being said, blockchain has been around for a long time, never having met you, i'd also jump to the conclusion that the odds of you running a vulnerable system, having a malicious plugin, running a virus, having your credentials or seed phrase stolen somehow are larger than the odds of a vulnerability in blockchain's system. Mind you, i'm talking about odds, not certainty's... Like i said, i have never met you, i have no proof, i haven't seen anything about you => It's just statistically speaking from my rather lengthy experience in this community, i'd say the odds of the problem being on your side are bigger than the odds of the problem being on their side... I try not to victim blame... It doesn't really matter if it was blockchain, a virus, a plugin, an OS vulnerabilitly... It was awefull for you to lose your funds, and it's defenately somebody else's fault (i'm not being sarcastic here!). Anyways, it was a rather expensive lessen for you, i'd recommand to switch to a more secure wallet... Pop $100 and buy a hardware wallet. If not, take an old pc, remove the network card and install a cold (air gapped) wallet. Or learn about paper wallets (do be carefull, you need to take caution and follow the proper procedure to create one of those) Title: Re: BTC hacked from blockchain wallet Post by: sunsilk on August 29, 2019, 06:56:17 AM I've used blockchain.com and there's a verification everytime I log in, it doesn't go directly to my wallet. Having that said about the notifications, there's an email notification before proceeding.
Thank you, there was no email notification, and, right, they couldn't get my private keys, the true reason was blockchain.com security breach, which they never admit. If you have checked it already and no notification has ever found. Did you looked at the other folders of your email? sometimes it's on spam folder and other unnecessary folders of our email. Otherwise, this is like the case that I've seen before that his funds were retrieved by someone although he's really technically aware of what he does and knows how to protect his funds including private keys, recovery phrases and login details.Title: Re: BTC hacked from blockchain wallet Post by: Thirdspace on August 29, 2019, 08:55:05 AM @bxmail can you tell us your bitcoin address, a transaction id, and a full story?
it would be more helpful if you can share the story from the beginning about how you received the bitcoin, when you realize you lost it, and what you do with your computer during that time? did you just create the account recently? any information can help us figure out what happened to your bitcoin Title: Re: BTC hacked from blockchain wallet Post by: odolvlobo on August 29, 2019, 09:00:11 AM Quote Check your email, whenever you login or have new transactions from your blockchain account they usually send out notifications.

Title: Re: BTC hacked from blockchain wallet Post by: NeuroticFish on August 29, 2019, 09:15:00 AM I will never use again and will discourage other people to use your service. Good. All the others said is correct: there's much bigger chance that your private key was "leaked" than something on their side. However, the first thing to do is to check your address(es) with another block explorer to make sure indeed your funds are gone and there's no other issue. About the "leak", there are a lot of ways to happen: from malware and key loggers to accessing a phishing site or storing the data in e-mail, cloud services, or somebody you know physically accessing (your computer/account, or the paper where it was written onto). As you can see, all are on your side (and against you) OP. But as started: good. Don't use online services to hold your money, especially if you don't believe in their safety (and blockchain.com is old, big and targeted by a lot of phishing). Use something safer. If you don't plan to spend, generate safely(!) a paper wallet and put your (next) bitcoins there. Or use a hardware wallet. Or use air-gaped cold storage, already an USB stick with Tails can do that if you make sure it'll never go online and read how to properly use cold storage.

Sorry for your lose. Title: Re: BTC hacked from blockchain wallet Post by: Lolox on August 29, 2019, 10:25:11 AM This is one of the risks of having digital assets in crypto. You are very upset with losing your assets because if it is made money is also very decent. Actions like this sometimes we also don't realize because we feel that the private keys are stored securely.
This obviously becomes a lesson for you and provides information with other users. So for the future be more cautious in storing digital assets. Title: Re: BTC hacked from blockchain wallet Post by: Nadziratel on August 29, 2019, 10:32:06 AM A similar incident happened to me about a year ago and unfortunately I didn't get any help from Blockchain support. I mean, I'm sorry, but I don't think you can find a solution.
Still, think twice if there is a possibility that the private key may have been stolen!

Having that said about the notifications, there's an email notification before proceeding. They really have some issues, for example on one of my account, I was always unable to log in even after email verification, that was happening only on one wallet, others are still working fine.Thank you, there was no email notification, and, right, they couldn't get my private keys, the true reason was blockchain.com security breach, which they never admit.

But there would be some issue from OP's side, if there is security breach on Blockchain.com then not only his but a lot, really a lot of wallets would be hacked, security breach can't get only one user's account into other's hands, breach gives access on some part of wallets. Hard case OP, can you think more deeply and remember, what happened? Did you install unknown antivirus? Pirate windows? Title: Re: BTC hacked from blockchain wallet Post by: Janation on August 29, 2019, 11:06:06 AM I've been using an online wallet and I don't have a problem.
These kinds of sites have their own security, you can always connect your email, some have their 2FA, some even require a phone number and I am wondering how can someone access your wallet without you being notified of that. Two points to consider, it is either your fault or the sites fault but I don't think the site will just let someone use your balance without logging to your account. Title: Re: BTC hacked from blockchain wallet Post by: dkbit98 on August 29, 2019, 11:37:51 AM This is exactly why I DO NOT recommend anyone using Blockchain.com or any similar online wallets.
It is much easier for hackers to get your information, or website can be hacked. Best thing is to have your own private key that never touches any internet website. I consider them similar like exchnanges, even if they are more secure. Best use some cold wallet (hardware or desktop), and double backup seed/private key. Sorry to hear what happened to you... and I hope you will get much more Bitcoin in future! Title: Re: BTC hacked from blockchain wallet Post by: leftgirly on August 29, 2019, 11:41:06 AM You many not have secured your wallet well. Once the funds was in your wallet and you have the personal private keys to the wallet then it would be very difficult for another person to conduct transaction you wouldn't know about it. It seems the blockchain wallet has been compromised by someone who know about your private keys.

Two points to consider, it is either your fault or the sites fault but I don't think the site will just let someone use your balance without logging to your account. Sorry, but this logic is flawed... It's not because you didn't have a problem with online wallets (yet) that they're safe to use. It's perfectly possible for a hacker to get his/her hands on the xprv, the seed phrase or the derived private keys (sometimes even without using the gui), in this case no email security, sms, 2fa, biometric security will help you... As soon as a hacker can derive private keys belonging to addresses that "belong" (for a lack of better terminology... When using online wallets, your funds belong to the wallet company) to you and were funded, he'll be able to rob you (even if the online wallet goes down). Bottom line: "if you're not (the only one) in controll of your private keys, you're not (the only one) in controll of your funds", this is true no matter which company, which 2FA measures, which guarantees,...

What you can do now is move on,try to use this experience to be safer next time and prevent being a victim again. Maybe it would be possible if you could recall what did you do prior to that incident (any information would help) so that the community could help analyze what happened and give further suggestions and recommendations. :) Well the damage has been done but of course this realizations will help Him and others to skip same scenarios in future for the benefits of allTitle: Re: BTC hacked from blockchain wallet Post by: Lapatai on August 29, 2019, 12:38:11 PM To avoid something similar in the future I would recommend storing BTC in cold wallet, write some super complex password, write it on the sheet of paper and hide somewhere (don't take photo of it and save to your PC). Store only small amounts of BTC in everyday usage wallet (I would prefer one with Google Authenticator).

Title: Re: BTC hacked from blockchain wallet Post by: audaciousbeing on August 29, 2019, 02:48:58 PM Its unfortunate that they would not own up to the responsibility of their infrastructure being compromised one way or the other because doing that to them would be bad for business as they know that words would quickly spread fast over the internet because paying you back would mean them admitting of not keeping your funds safe as they have promised millions of their clients all over the world.
This is one issues I have with crypto market despite the reoccurring report of this particular service provider have been determined to be responsible for quite a number of loss of funds but they will go away with it because the market does not have control or overseeing body to put its activities in check.

I don't understand since you never posted a mistake in the OP, you also said it might be a security breach but the thing here is that the hacker might already hacked you log in. Better store your balances in a more secure wallet, I don't think this statement is new since there are a lot of threads here saying that it ia not safe to store on online wallets or some called it hot wallets. Title: Re: BTC hacked from blockchain wallet Post by: Lucius on August 29, 2019, 03:18:36 PM bxmail, can you tell us where you kept your wallet ID and password?

Do you remember last time when you access your wallet, are you use link to blockchain.com from your browser bookmarks, did you click on it from your e-mail or you search for it with search engine? It is also posible that you somehow infected your computer with keylogger or RAT (remote access trojan), can you tell us do you use any antivirus or other security software? I see you posted in Web Wallets board also, but in case you missed it, people lost coins from this wallet long time ago in cases like this : https://bitcointalk.org/index.php?topic=2488493.0 Title: Re: BTC hacked from blockchain wallet Post by: killat on August 29, 2019, 03:39:23 PM I'm sorry for your loss, mate. If your Blockchain account has been compromised then I'm afraid there's no chance to recover your funds back.
In order to avoid this to happen in the future try to use a hardware wallet instead of holding your private key on your PC. Title: Re: BTC hacked from blockchain wallet Post by: MrCrank on August 29, 2019, 04:05:48 PM @bxmail can you tell us your bitcoin address, a transaction id, and a full story? it would be more helpful if you can share the story from the beginning about how you received the bitcoin, when you realize you lost it, and what you do with your computer during that time? did you just create the account recently? any information can help us figure out what happened to your bitcoin My BTC address: 1FgpbfQ8nVMS523Btnyv3rxhF7YxtiEdr7 Created with blockchain.com 2 years ago. Funds received more than a year ago. It was safe during all period, I always paid much attention to security. The loss was realized yesterday, Aug 27, 2019 morning, I turned on computer, checked my e-mail as usual (again there was no notification from blockchain.com), before that, the computer was turned off all night. 2019-08-27 07:03:08 Amount: 0.035 BTC (350 USD) Transaction ID: 4d412c58ab3dba8a138557e41e9ace1c8b36ee3d44107a930c8f31f0198d2b93 Recipient address: 1PdXxtu8Laq773RXT5q5pp6qtaG3HvSw2r Last TX showed 1L5tLc6ayc3RXAyicHRv2c2uSNVJzoP4Yp, this address recieved 77.7 BTC. it's not easy address.. ::) Title: Re: BTC hacked from blockchain wallet Post by: Thirdspace on August 29, 2019, 06:19:47 PM The loss was realized yesterday, Aug 27, 2019 morning, I turned on computer, checked my e-mail as usual (again there was no notification from blockchain.com), the transaction was made about the same time you're checking your email but it gets confirmation almost an hour later, if you had acted fast you would have saved your coins can you remember what emails you were reading/opening at that time? did you open or click any link in your email? did you check your blockchain.com wallet before or after reading your email? Title: Re: BTC hacked from blockchain wallet Post by: Mpamaegbu on August 29, 2019, 06:40:59 PM Once the private key is in your hands you're responsible for the funds. Truly speaking someone might have known about your private keys and passwords. Myself too have experienced loss of funds from my blockchain wallet which happened due to my negligence of keeping private keys securely. Quote If you carefully read my post, I always double-check and secure it, no one has access to my private keys or passwords. This is the case of the blockchain wallet security, please take some time to read similar posts, it happens these days on a regular basis. This really is a frustrating experience I must say. I feel your loss. But I also think what bxmail said isn't wrong. I have used blockchain for close to three years now but I haven't experienced such. This is where I encourage people to always access their wallet through the app and not through web. In all,, we should at all time safeguard our PKey and passwords. You never can tell who is lurking and waiting for the unguarded hour to strike.Title: Re: BTC hacked from blockchain wallet Post by: BitValve on August 30, 2019, 01:33:14 AM Unfortunately it’s very hard, if not impossible to prove that it’s blockchains fault. The most probable scenario is that you have been phished, for example when googling “blockchain”, there maybe Advertisements on top of results, which appear to be the same site, but in the end it’s somthing very close like “blockchian.com”.
Title: Re: BTC hacked from blockchain wallet Post by: bitbenzhong on August 30, 2019, 03:03:11 AM becareful your private key.that's important :P
Title: Re: BTC hacked from blockchain wallet Post by: barbara44 on August 30, 2019, 08:08:19 AM What would you have had them done, they should refund your money because they are binance with safu fund? My dear, it is true that they are saying, there are so many hackers right now that would gain access to your account at any time if you are careless with your passwords or careless with the website that you go to.
I am also sorry to have heard your story, and thank God they dint steal more than that, there should be some sort of way that you can really trace it and I am not sure that is their problem, if it was network bridge, I am sure that they would have been able to sort it out for you, and which may have also affected thousands of their users also, and you would surely have seen so many complains. I think you have to look for a more reliable way to secure your coin then if you no longer trust blockchain. Title: Re: BTC hacked from blockchain wallet Post by: Leonardo7 on August 30, 2019, 10:05:40 AM Sorry about this, some persons usually get hacked on blockchain .info, some users said they had activated SMS option as against a more secured google autenticator, and another had saved his private keys online, which is unsafe and not recommended to do so. Try to have a separate email from bitcoin login, and never use the same password, you may want to get phone for for the sole purpose of sending and receiving bitcoin and never download anything there. Alternatively, get a hardware wallet which is the most secured provided your keep the private keys safe.
Title: Re: BTC hacked from blockchain wallet Post by: bxmail on August 30, 2019, 10:21:33 AM Sorry to keep you waiting for the answer. I was trying to identify the thief through Huobi, cause the transaction finally ended at 1L5tLc6ayc3RXAyicHRv2c2uSNVJzoP4Yp Huobi account, that probably accumulates multiple other thefts.
Back to security questions, I can assure you that all the keys, passwords, IDs are securely stored, so no physical contact of possession possible. I never click on e-mail links, phishing sites, extensions or other potential malware source. My computer was turned off all night before I turned it on next morning when realized the hack. I have also double-checked it for viruses and access ports protection, so it's totally clean, not infected with all ports being safely closed. I really don't know at this point what could have happened, but i'm sure it's not my fault. It may still be the case like in the link you submitted https://bitcointalk.org/index.php?topic=2488493.0 Title: Re: BTC hacked from blockchain wallet Post by: Lucius on August 30, 2019, 10:48:41 AM Sorry to keep you waiting for the answer. I was trying to identify the thief through Huobi, cause the transaction finally ended at 1L5tLc6ayc3RXAyicHRv2c2uSNVJzoP4Yp Huobi account, that probably accumulates multiple other thefts. No problem, it would be really great if something could be done from Huobi, they can freeze that address and conduct an investigation, so there would be hope for a refund of stolen coins. Regarding everything else in your case, you can never be completely sure that the failure did not come from you, but this does not mean that the fault cannot be on the other side. The problem is in proving that blockchain.com is have some security glitch, I doubt they would ever admit it. Did you see this thread? https://bitcointalk.org/index.php?topic=5157460.0 Users who are convinced they lost 400 Bitcoins due to some vulnerability had a plan to sue blockchain.com (ex info), you can contact them for more info. Title: Re: BTC hacked from blockchain wallet Post by: mocacinno on August 30, 2019, 11:41:27 AM It's good to see you taking your case to huobi, but like i said: do be carefull you're not attacking somebody innocent that has used a mixing service to regain some anonimity...
I just read an interesting blogpost that might be relevant to this discussion, and the discussion link posted by Lucius (https://bitcointalk.org/index.php?topic=5157460.0) https://googleprojectzero.blogspot.com/2019/08/a-very-deep-dive-into-ios-exploit.html Tl;DR; version => vulnerabilities that were fixed in iOS 12 allowed hackers to gain access to iphone devices that merely surfed to an infected webpage... Nothing else: just visiting an infected webpage was sufficient to give the culprits full access to your phone (emails, files, passwords,...). There is nobody that can ever be 100% sure they're running a completely clean system... This does NOT mean that we can be sure there are no vulnerability's on blockchain's side... Just that everybody saying that they're 100% sure their system was clean, eventough they used it to visit blockchain.info (so it's an online system) is misinformed. I know the OP never said he used iOS, but other platforms might have similar vulnerability's. Title: Re: BTC hacked from blockchain wallet Post by: jeraldskie11 on August 30, 2019, 03:11:33 PM There are many happenings in this in any different situations. If someone knows your account information of Blockchain wallet, there is still a possibility to be hack, how? In this way, if your information in blockchain wallet and the information of your email is the same you will get hacked by the hackers when they know that 1 information because they can confirm in your email to withdraw the funds. So keep safe your email because that is one of the most important especially for recovering funds.
